Wireless Noise Canceling Stereo Headset
WH-CH720N
The effect of noise canceling is not sufficient.
Make sure the noise canceling function is turned on.
Adjust the headset into a comfortable position.
The noise canceling function is effective in low frequency ranges such as airplanes, trains, offices, near air-
conditioning, and is not as effective for higher frequencies, such as human voices.
When the Adaptive Sound Control on the “Sony | Headphones Connect” app is turned on, the wearer's actions, like
walking or running, are detected. The noise canceling function is automatically adjusted and the Ambient Sound
Mode may be activated according to these actions.
To make the most of the noise canceling function, turn off the Adaptive Sound Control, and try to turn on the noise
canceling function manually when you need it.
With the “Sony | Headphones Connect” app, check the setting of [Ambient Sound Control]. If it is set to [Ambient
Sound], the effect of noise canceling is reduced. Set it to the noise canceling mode.
